CINDER
CINDER is a mechanics-first Python model for rubber V-belt continuously
variable transmissions (CVTs). The installed package is imported as cinder.
CINDER models the CVT as a mechanical plant with explicit pulley geometry, belt contact, clamping mechanisms, inertias, shaft boundaries, and hybrid contact/operating modes. The package is independent of the CVT-Simulator web frontend and backend.
Install
python -m pip install cinder-cvt==1.0.0
Verify the installed distribution:
python -c "import cinder; print(cinder.__version__)"
Expected output for this release:
1.0.0
Runtime dependencies are intentionally small:
- NumPy
- SciPy
Public Python API
CINDER v1 has three supported import surfaces:
cinder— core mechanics, composed systems, shaft boundaries, hosts, and hybrid execution entry points.cinder.contracts— versioned JSON-safe assembly/simulation documents, validation, schema information, and result projection.cinder.studies— supported static geometry and actuation study APIs.
Modules beneath these public surfaces remain available to advanced users, but deep implementation-module paths are not the compatibility boundary for v1.
Run the reference example
The source repository contains a current fixed-pivot Baja reference case:
python cvtModel/examples/quickstart.py --run
The example imports the installed cinder package. It does not require the
frontend or backend.
Documentation
- Getting started
- Public document contracts
- Simulation-document JSON Schema
- Geometry study API
- Actuation study API
- Fixed-pivot flyweight mechanics
- Hybrid impact mechanics
Repository-only material
The monorepo also contains launchTools, tools, validation artifacts, the
backend, and the frontend. Those directories are useful to the project but are
not part of the cinder-cvt wheel or source distribution.
